Density is mass over volume. The density of iron is given in g/cm³
we have to first convert g/cm³ to kg/dL.
1000 g = 1 kg and 100 cm³ = 1 dL
the mass of 1 cm³ = 1 g
the mass of 100 cm³ / 1 dL = 100 g
then mass of 1 dL in kg is = 100 g / 1000 g/kg = 0.1 kg
volume of 0.1 kg is 1 dL
therefore density of iron is 7.86 g/cm³ x 0.1 kg/dL / g/cm³ = 0.786 kg/dL
volume of iron having mass 0.786 kg is 1 dL
then volume of iron having a mass of 4.62 kg is - 1 dL / 0.786 kg x 4.62 kg = dL
volume of iron is 5.88 dL
